PICOT EDGING FOR FABRICS.

To all whom it mayconcern:

Beitknown that I, LANSING ONDERDONK, a citizen of the United States,residing at New York, in the county oft-New York, State-ofJNew York,have invented certain new and useful Improvements in Picot Edgingsfor'Fabrics-, of"which the following is a description, reference beinghad to the accompanying drawing and to the figures of referencemarkedthereon. 1 1 "The invention relates to'new and useful improvements inedgin'gs' for fabrics, and more particularly to a picot edging, that isan edging wherein-there are at intervals spaced projecting loops.

An object of the'invention is to provide a machine-constructed-- picotedging, that is, an edging for fabrics wherein the overefdge stitchesare formed with a series of spaced loops which'project laterally beyondcertain of the over-edge stitches and :the' ed e of the fabric. 7

the invention is to provide a picot edging'of the above characterwherein one ofthe stitching threads is formed into loops which projectlaterally beyond certain 5. of the i over-edge stitches andtheedgeof-the fabric.

' Th'eseand othenobjects will in part be I obvious and will in part behereinafter more fullydes'cribedzf In thedrawi-ngs I V Figure 1 "saviewin plan showin'ga fabric having my improved picot edging-applied'thereto, and also showing" the method ofma'king the same; 7 7

"The invention conslsts broadly ama chine-constructed. picot edgingi=-that 5 is, i an edging wherein certain of-the threads -are formedintoenlarged loops which "aresofdis-I posed as to project' 'latera'llyfrom'i the other loops of the overseamingLst-itchesand later ally fromthe edge of the fabridand in'the plane offthe fabric." This edging maybe con-1 structed from two-thread -orj'three-jthread overseamingfstltches 'and either the needle thread or one:ofthelooperthreads-maybeformed into loops which project beyond the edgeof the fabric sofas toproduce-this p'icot edging. The edge'o'fthe fabric may also be foldedback Within the limits of the over; seaming stitches, if desired, sothat-the -overseaming stitches will inclose the foldededge of "thefabric. H

Referringmore in detailto Figs lto 4,

inclusive,'- of the drawings, my improved" picot edging consists of twothreads;: a

needle thread land alooper thread 2; 1A fabric, indicate'd at F, has'the edging formed thereon. The needle thread is'form'ed into loops3-which are passed down' through the fabric at. the points 4, and theseneedle. loops are carried-tothe edgeofthe fabric. The looperfthread is'formed into loops 5 which pass throughthe respective loo'ps formed inthe needle threads. These looper I thread loops are laid on the upperface of the fabric, and the needle thread 'loop asses down through thelooper thread loop. This is a well-known form of two-thread over-edgeseam and will not need further descri tion. g j v In B lof thedrawings,I have shown the needle at N, the threaded looper at L, and the s readerfor spreading the needle loop at Cooperating with the needle,

Thisloop retainer is timed so as to engagea needle thread loop at everythird-stitch or puncture of the fabric by the needle. TlllS retainerholds the needle thread loop when the stitch is being set, so that theresultant loop is enlarged or extended, as clearly shown at 6 in Fig- 1.These enlarged or extendedloops 6 project beyond, the other overseamingstitches and the edge of the fabric and lie in the plane of the fabrlc,as shown diagrammatically in Fig. 4.

41 have produced. an edging, therefore, wherein the overseaming stitchesencircle the edge of thefabric-and'at intervals of every three stitches,as shown in Fig. -1, the needle loop is enlarged and extended andprojects fromthe edge of the fabric, thus forming thepicotedging. WhileIhave shown inFig. 1 the loops projecting from the edge of the fabric atevery third stitch,

it'will be understood that this spacing of the loops may be'variedwithout departing from the spirit of the invention.

In Fig. 5 of the drawings, I;have shown a two-thread overseam of thecharacter described in connection with 'Figs. 1 to 4, in-

elusive. In thisshowing of the invention, however, the'retainer'Rengages the looper thread between the loops which are projected throughthe needle thread loops and holds the thread, out so as to form aprojecting loop in the looper thread. The projecting loops areindicatedat 7 in Fig. 5 of the drawings. These loops are shown as being: formedat every third stitch or puncture ofthe fabric by the needle, but

it is obvious that they may be spaced any desired number of stitches orneedlepunctures. This may be accomplished by varying the timing of themovementof the retainer. I

In Fig. 6 of the drawings, I have shown diagrammatically the arrangementof threads shown in Fig. 5, and it will be apparent that the projectingloops 7 lie in the plane of the fabric. 7

In Fig. 7 of thevdrawings, I have shown a slightly modified form. of theinvention illustrated in Figs, ,1 to 4, inclusive, in that the edge ofthe fabric is folded back at F.

- This foldingback of thevedge of thefabric is. within the limits. ofthe overseaming stitches, and the overseaming stitches enside of thefabric a looper'thread' 8 is formed into a series of loops which arepassed through the respective needle loops and these loops 8 are broughttothe edge ofthe fabric where the looperthread 2 is formed into aseriesof loops, each of which is passed through a loop in the looperthread 8, and the looper thread 2 is laid on the upper face of thefabric and secured by the needle threadas described inconnection withFig. 1. V In this form of the invention shown in Fig. 8, in place" ofthe spreader, a thread carrying looper L is used and the retainer istimed so as to engage the looper thread,-of;this looper L; The retainerenlarges "or extends the loops into projecting loops '9 which are shownas spaced three stitches or three needle punctures apart. This spacingof the loops may be varied, as. abovestated, 5 i

In F'g. 1 0 of the drawings, I have shown an edging having picotloopsformed'which is similar to that shown, in Figs: 8 and 9, with theexception that the tension on the threads have. been changed so that theneedle loopsare drawn to the ed e of the fabric and the threadhaving'the picot loops formedtherein lies wholly along the edge of thefabric. a

Itwill also be understood. that the other looper thread, as inthetwo-threadstitch, may be extended, if desired, to form the projectingloops.

From the above, it will be apparent that I have provided a picot .edgingwhich may be made by a sewing machine, andwherein one of the stitchingthreads of. theoveredge stitches is formed into loops which are extendedor enlarged so as to J project laterally from the edgeof the fabric andlie in the plane of the fabric. These loops are spacedso'as to give theappearance of the well-known picot edging. Y

By making the picot loops from the me dle threads which form theoverseaming stitches, said loops are locked so that one loop does notdraw thread fromthe' next adjacent loop ifastrain is placed-thereon,that is to say that the thread betweenthe loops is interlocked orconcatenated-"with the stitches intervening between the picot loops, andthis holds the picot loops at a predetermined size. 4

Having thus described the invention, what is claimed as new is Thecombination of a fabric and a picot edging therefor, consisting of aneedle thread formed into a series of loops extending through thefabric, a looper thread formed into a series of loops extending throughthe needle thread loops and over the edge of'the fabric where saidlooper thread loops are entered by the needle loops prior to the passingof the same through I the fabric, one of said threads being formed intoloops projecting laterally beyond the i edge of the fabric, said lastnamedloops being spaced two or more thread concatena- 15 tions apart. IY In testimony whereof I affix my signature, in the presence of twowitnesses.
